Congress passed the Budget Control Act of 2011 with bipartisan support, and signed into law by Obama... which cut over $400 billion from projected defense spending over ten years. The act also led to sequestration, which slashes an additional $495 billion from the defense budget, for an overall total of almost $1 trillion in cuts.
The deal was, conservatives would agree to military cuts while the libs would agree to cuts in govt social spending. The idea was it was a worst case scenario. Leadership collapsed though and we’re stuck with the military cuts and the Democrats got their obscene spending on the non-military side somewhat restored.
Boehner screwed us all.
